' 15 3-18, 2, showing the driving mechanism for driving the 'pinion shaft which operates the Geneva movement and the gear "cam.

In the manufacture of shell buttons, there isgreat' liability of breakage, which can be best overcome by avoiding all possibility of improper relative movement between the button-blank carrying part and the operat- 1 ing tool which works uponv the shell mate'- rial. In the machine shown, the chuckor holdingdevice of the" turret mechanism first stops at a convenient point, preferably directly in front ,of the operator, to receive the blank, which is placed in position preferably by hand. The chuck then moves in front of the roughing tool, where it stops. Thereupon the roughing tool roughly forms the blankand backs off. The chuck then moves forward to the next tool and stops, which finishes the forming operation, and thereafter the chuck moves step by step in front of successive fancy-pattern tools and hole-drilling tools, and finally to discharge position, remaining;stationary at each point while being operated upon.

- As herein shown, there are eight work holders 1, all alike, for holding the blanks as they are carried successively, forward to the {successive tools to be operated upon, said "work-holders being mounted on a spider-like carrier comprising a ring 2 and radial arms 3 extending from a-hub 4 at the upper end of a sleeve 5 driven" byithe i Geneva 'm'ovement mechanism shown in Figs. 2, 1618. This sleeve is mounted for convenience, on a central or main drive shaft 6 journaled atitslower end ina cross bar 7' of the main frame and at its upper endin an overhanging yoke 8, which-Sis secured at its opposite ends 9 to the main bed plate'li) of the machine. This shaft 6 carries at its upper end a bevel gearfll which drives the work-carrying mechanism' of each work- 1 I holder, and, as these areall alike, a descrip tion of one will sufiiceforall. Referringto Figs. 2, 9-12, it will be seen that I provide a chuck having a hollow shank .12 and split at its outer end into a plurality of gripping jaws 13 to hold a blank l l asbest shown in Fig. 10. Said shank is internally threaded and engaged by the threadedend 15 of a spindle 16 shouldered atfi'l7 toreceive the thrust of a spring 18 which bears at its opposite end against a shoulder 19 of an inclosing sleeve 20 splined to spindle 16. At its outer end the sleeve 20 is internally beveled at 21 to fit the correspondingly beveled or conical periphery of the chuck jaws 13 so that the normal position of the latter under the influence of said spring 18 is closed in gripping engagement with the work. To release the work or open the jaws to receive work, the requisite relative movement between the jaws 13 and the sleeve 20 is preferably accomplished by moving the sleeve, the spindle 16 being held at all times against endwise movement by a stationary fork or collar 22 extending upwardly from a block 23 secured to the adjacent arm3 of the spider or carrier, which bears against an end collar 2% at one side and at its other sideagainst'a ball bearing25 and flange 26 on said spindle. Splined on the sleeve 20 .is a friction cone 27 for coupling the sleeve 20-and spindle 16 with their driving gear 28 which is driven by the gear 11 previously described, said gear 28, being provided with an internal conical driving surface 29 for receiving said cone 27. The latter is actuated by a forked lever 30 pivoted at 31 to the block 23 whose fork travels in a groove 32 of said cone, the opposite end of said lever 36 being provided with a cam roll 33 actuated by a cam 34 in opposition to a spring 35. The cam 3%, see Fig. 14, is provided with a raised portion 36 which moves the cone 27 back against a collar or flange 37, Fig. 9, secured at the inner end of the sleeve 20 and thereby retracts the latter from the gripping aws 13 so that the latter are permitted to open as the chuck arrives at the discharging positionand remain open until after it leaves the starting position or front of the machine at 38, whereupon a slight depression 39 in said cam, permits the cone 2'? to move forward slightly from the collar 37 so that the spring 18 can close the work-holding chuck into gripping engagement withthe work 14, and thereupon a depression 4C0 in said campermits said cone-27 130 move still farther forward, this time moving toits extreme forward position in driven engagement with the driving gear 28, which, as herein shown, continues to drive the work-holder while the work is at the first two stations or being operated upon by the first two tools. In other words, the work continues to be positively rotated by the gear 28 until the preliminary shaping or forming operation is completed. As soon as this forming operation has been completed and the work-holder has started to its next position, a raised cam surface d1 moves the cone 2'? back out of driven engagement with the driving gear 28 in which position it is thereafter held until ready to be discharged. As it is necessary that the work shall remain in absolutely unchanged axial position while being operated upon at the remaining stations or halts in its travel, I. provide a second stationary cam d2, roll 43 and lever 44 pivoted at 45 and actuated in opposition to said'cam by a spring46. This lever has awvedge shaped upper end at? to engage between the beveled ends 48, 4-9, Figs. 11 andl2, of friction clamps or jaws 50, 51 which embrace the spindle 16, being pivoted together at 52 above the same and held under tendency to clamp against the spindle by a sleeve spring 53 mounted on a bolt 54 and held under tension by nuts 55. Thus when the extended portion 56 of said cam l2. engages said lever at, it operates to shove the wedge-end e7 in between the ends 18, 49 of the clamping jaws so that the latter are out of engagement with the spindle 16, but as soon as the work has passed the first two stations, the depressed portion 57 of said cam 42 permits'said lever at to swing inwardly under the influence of its spring 14, thereby partly removing its wedge-end 47 from between said jaws 50, 51 so that the latter are held in gripping engagement with the spindle 16 by the spring 53, thereby preventing the button-blank from changing its axial position to the slightest extent while passing step by step to its succeeding positions. The jaws 50, 51, when in gripping engagement with the spindle 16 are held from dislocation by the wedge-end lfiwhich at this time still projects some little distance in between the ends 48, 49.

The work-holder first moves from the starting position to position to be roughformed by the rough-forming mechanism at station 58 and then to position to be finished in form by the mechanism at station 59, and as the mechanisms at these two forming stations are both the same, a de scription of one will suffice for both. Referring to Figs. 3, 4c, and 5, I have mounted on the bed 10 a base 60 adjustably clamped on a dovetail way 61 by set screws 62, and on this base is mounted a table 63 also preferably supported on a dovetail way 64, (shown as forming a part of the base 60) on which the table 63 is reciprocated by a screw rod 65 to which it is connected by a nut 66 whose tongue 67 engages said table. The rod 65 is preferably provided with an adjusting head 68 and is threaded into the nut 66 so as to between said'rod and the table to bring the tool into accurate adjustment with relation to the work. The rod 65 is moved lengthwise by a carriage 69 whose T-shaped flange 70, best shown in Fig. 8, (which, although shown in connection with the drill head, is exactly thesame for all the operating tools of whatever kind they may be) is guided. in a recess in the bed and travels on an alining shoe 71, being actuated by a cam roll, 72

permit relative adjustment cam 7 5 in a cam 7 6 provided peripherally with gear teeth 77 in mesh with a pinion 78 fast on a vertical shaft 79 whose worm wheel 80 is driven by a worm 81-and beveled gears 82, 83 fast on the main shaft 6.

The-shape of the tools 81,85 at the first and second stations, 2'. 6. stations 58, 59, will conform to whatever general shape of button it p is desired to make from the blank. The

tool is mounted in two normally rigid arms 86, 87, the former being immovable with relation to its support 68 and the latter adjustable on said support in order to approach the arm 86 as the tool shortens in use and has to be moved forward. The tool is held in these two arm's by'set screws 88, 89 and clamping plates 90, as best shown in Fig. i. The set screw 88 holds the rear end of the tool rigidly and immovably clamped, but a spring 91 coeperates with the forward set screw 89 in yieldingly clamping the forward end of said tool, so

that as the rear arm 87 is fed forward step b by step, the tool can movewith relation to the front arm 80 although still held properly clamped thereby. This forward feedingof the tool is of considerable practical importance. 1 have found that one ofthe serious causes of breakage in themanufacture of pearl buttons is due to the dulling of the roughing tool and finishing tool, and also to some chips on the work which wedge under the tool. and against the work, tending to fracture the latter. Accordingly have eliminated the accumulation of chips and dust on the work by standing the blank edgewise in the machine and arranging'the tool to approach. the same horizontally as distinguished from having the blank horizontal and the tool brought down onto it vertically, and 1 have eliminated the breakage due to the wearing of the tools to an imperfect cutting edge by providing the tools with a forward step-by-step movement, preferably automatic, which moves the tool forward an almost infinitesimal increment greater than the wear caused by a predetermined amount of cutting, and 1 move periodically in front of these cutting tools a sharpener -which grinds off the tool to the extent of this small increment, so that the tools are not only kept sharp but are ke t in absolutely true position with relation to the blanks. Preferably this forward feeding of the tools and sharpening thereof takes place once for every eight buttons made, although this in practice depends somewhat on the kind of button, button-stock, and tool.

, step feeding movement is accomplished by a feed screw 92 mounted to rotate at 93 in extent to the accumulation of p The step-by the table or tool carriage 63'but held against longitudinal movement, saidscrew having threadedengagement w th a depending lug or nut 941fast on the under side of the base 95 of the movable arm 87 which travels on a dovetail 96 formed on the upper side of the tool carriage. At its outer end the feed screw 92 isprovided with a worm gear 97 in meshwith a worm 98 whose shaft carries a ratchet 99 engaged by a pawl 100 pivoted at 101. on a stat onary bracket or ear 102, so

that each time thetool carriage 08 is reciprocate'd by the cam 75,"the tool isfed forward thedesired increment. T o' perm'it this feeding movement tobe accomplished by hand whenever desired, a hand wheel 103 is pinned onto theouter end of the screw shaft 92 and provided with a locking bolt 10% for locking the worm gear 97 to said shaft and unlocking the same when the bolt is pulled out by its handle end 105 agains't'its spring 106. 7. The hand wheel'has a handle or crank 107. While ordinarily, the automatic feed ofthe tool is' suiiicient', the handfeed is de sirable in case a badiplac e should develop in a tool or for any other reason it should become desirable to give the tool special attention. 1 v K The sharpening or truing deviceis preferably an emery wheel or any kind of grinding wheel 108, and is preferably mounted on the spider ring or ,turretring 2 in a journal bracket 109, see Figs. 1 and 3. Thisbracket has two oblique bearings at right angles to each other, as herein shown, one bearing in which thespindle 111 of the grinding wheel 108 is mounted within and keyed to a sleeve 112 which carries at its outer end a beveled gear 118 driven by a gear 11-4:

on a shaft 115 journaled in the other oblique bearing 116-and carrying a pinion 117 at 1ts outer end in mesh with the adjacent oblique peripheral gear teeth 118 of the drivingge'ar 11, whereby the grinding wheel 108 1s maintained 1n continuous rotation. 1

The normal position of this grinding wheel is back, so as'not to interfere with thesucceeding tools at the subsequent stations, being held in its backward position by a spring 119 on the spindle 111 and moved forward at the requiredtimes for truing' the roughing and finishing tools 8e, 85 by a i cam 120 last on the bed plate 10 and engaged by a camroll 121 at the lower end 12-2 of a lever pivoted at whose upper end 121- is provided with an abutment screw 125 which bears against the lower end of the spindle 1111 for moving it inopposition to its spring 119. 'This permits the utmost nicety of adjustment of the forward position of the truing or grinding wheel 108 whereby the latter is enabled to maintain absolute accuracy of grinding-ed e posiion' of the tools 8%, 85. The spindle 111 is supported by the abutment screw'125only 1 when in grinding position, the wheel 108 having a flange 126 which seats in a recess 127 during the remaining travel of said mechanism. I secure still further accuracy of finish and avoidance of breakage by providing means for insuring that the cutting tool shall engage the blank at the one critical point necessary for the best work. I have found that there is always one point on the blank where the tool will cut to the best advantage, this point depending upon the pattern of the button, the tool, and the angle, and accordingly, to adjust the cutting edge of the tool accurately to this position, I have made the tool carriage 63 in two parts, consisting of a lower part or table which directly engages the dovetail 64, and

.an upper part 128 pivotally supported at its outer end on center screws 129, the other end of the part 128 being accurately adjustable toward and from the lower part of the carriage 63 by a hand operated post or thumb screw 130 mounted to turn at 131 in the upper part and tapped into the lower part at 132, see Fig. 5. To prevent backlash or chattering of the tool, I provide said post with a fiange 133 and hold the upper part 128 continuously down hard upon said flange by a spring 134. r

In making the ordinary pearl or shell buttons, the tools to which the button is subjected after it has been turned down and finished to the right shape by the mechanisms at stations 58, 59 are the drilling tools, usually two or more according to the kind of button. In this more complete embodiment of my invention, however, I have shown the machine arranged to make fancypattern buttons. After the general or pre liminary shaping of the button at stations 58, 59, the work-holders carry the partially formed buttons to pattern shapers, herein shown as comprising two stations 135, 136. The particular kind of fancy-pattern tool shown at said stations is a grinder, which I have shown for the purpose of rendering this portion of my invention clearly understood, inasmuch as monly used for making fancy patterns, but it will be understood that any other kind of pattern-tool suitable for the given kind of button being made may be used, and also it will be understood that the particular order of arrangement of the various tools and stations may be changed according to the requirements of the particular kind of button or the preferences of the individual factory or user. At station 135 I have shown the grinder as composed of two parallel horizontal emery wheels 13? mounted onaver tical spindle 138 .vhose pulley 139 is driven by a band or belt 140 passing over guide pulleys 141 to a driving pulley 142inounted at the outer end of a shaft 143 whose pinion 144 meshes with the central driving gear drilling has been finished.

grinding tools are com tion of one will suflice for all.

83, which serves to drive all the pinions 144, there being one for each station from 135 on, see Fig. 17. At the station 136 I have shown a similar grinder, excepting that its emery wheels 145 are mounted to turn in vertical planes on a horizontal spindle 146 whose beveled gear 147 is in mesh with a drive gear 148 on a shaft 149. This arrangement is for making What is called a square-faced pattern button. Of course any other pattern grinders or other kinds of tools may be substituted for the grinding means 137, 145 according to the kind of button, as for instance a fish-eye button would call simply for one central grinder to grind the fish-eye, whereas a button with a checker-board face would call for a multiple-edge grinder at each place.

One ofthe commonest kind of buttons is shirt buttons, and these buttons are ordinarily sewed onto garments by means of buttonsewing machines, and the frequent breakage of the buttons and of the needles of the sewing machines is due to the fact that the thread holes are not uniform and accurately spaced. Accordingly one of the chief aims of my invention is to provide mechanism which will insure the absolutely accurate and uniform spacing and formation of the thread holes or eyes of the buttons. This is accomplished mainly by the mechanism already described which moves the work to a definite position where it remains while being operated upon, and which clamps the button as soon as its shape has been finished at the second station or position 59 and holds said button and its spindle 16 and sleeve 20 imn'iovably from that point until the final Two drill heads are herein shown, each operating a single drill at stations 150, 151. I have shown this simple form as the best means for rendering my invention clear to this feature, but it will be understood that the number of drills, and whether each station has a single drill or not, and also the number of stations, will. depend upon the button. As herein shown, I have provided for a two-hole or two-eye button, but buttons with four, siX, and various numbers of holes may be provided. for as already intimated. The drill heads are all alike (excepting'that they are so positioned that their respective drills bore the respective holes in desired relation to each other in the button), and hence a descrip- Referring to Figs. 68, I have shown a drill 152 mountedin a drill chuck 153 at the end of a spindle 154 journaled in eccentric bearings 155, 156 mounted in a hanger 157 (this same hanger and accompanying parts being also a part of the construction of the pattern-tool heads at stations 135, 136, and hence similarly designated) pivoted at 158 on a wide standard 159projecting upwardly scribed way 01, adjustment out at 108 to provide a serviceable in the case of the drills.

anechanism, as already from one side of a carrier 160 which is provided with a dovetail sliding engagement at 101 with a lmse1 2which corresponds to the base 60 of the previously described tool heads at stations 58, 59. A screw rod 163,

which corresponds to the screw rod 65, is tapped directly in the carrier 160 and adjusted by an adjusting head 161. The base is mounted for lateral adjustment ona dovetail way 165 the same as the previously debeing given in both instances by a screw 106 mounted to rotate in an up-turned end 167 of the adj a cent dovetail way. The way 165 and the bed 10 and the superposed parts are cut vertical opening for the driving belt 110 of the grinder at station 185 and a driving belt 169 at the following stations. This belt passes over a pulley 170 on the spindle 119 ofthe grinderat 130. The belt 189 at the drill stations passes over a pulley 171 on the drill spindles 151-. Said belt passes downwardly under guide pulleys 172 around a driving; pulley 1-1-2 on a shaft 113 (as already described).

-The han er 157 is mounted at its free end on althreaded post 178 vertically adjustable in a boss 1'71 by means of a hand wheel 175. This provides for a delicate vertical adjustment, which is especially important and In the adjustment is prodrill heads, a transverse bearings 155, 1a

vided by the eccentric which, for this purpose, have a connecting handle 176 by which they may be rotated much or little according to'the adjustment desired, and then immovably clamped by a clamping screw 177 which clamps together the ears 178. By reason of these various adjustments, each drill 1- 2 is brought with perfect accuracy to the position required for drilling its hole in the button-blank.

The step-by-step movement of the turret mechanism or work-holders maybe provided by any suitable means, the preferred stated, being a Geneva movement, best shown in Figs. 2 and 16, where it will be seen that thesleeve 5 which carries the 'work'holding parts 1, 2 8, 1- has keyed thereto a star wheel 179 whose dwells 180 and radial slot-s 181 cooperate with the pin 182 of a pin wheel 183 and its hub 18 1 having a usual cutaway side 18:) The mechanism already next to said pin.

described insures a high degree of accuracy, but to render the machine still more certain in positioning the work, I have provided, in addition to the Geneva movement and connected parts, a. positive, automatically centering, lock for the turret or work-carrying -head, said lock being herein shown as com- 186 fasten the shaft 79 which prising a. cam

Thereupon the the critical point for best results, is fed forward automatically to accomplish the rough shaping of the blank. As the work holder horizontal and the shaping tool engages the work in the same horizontal plane, the chips and dust cannot accumulate on the button but the latter is kept free and clean all the time, and because of this fact and also because there are no overhanging parts, the operator can watch the progress of the work at the cutting point at all times. As soon as the blank is rough shaped, the tool 84 moves back and the work moves forward one step, where it is halted in accurate position before the cutting tool 85, which operates thereon to accomplish the finish shaping operation in the same manner as the rough shaping was previously accomplished.

This is accomplished by the stationary cam 42 and the wedge-shaped end 47 of the lever 44.
